Patent DE-4305908-A1 (DE)
Title: Waveguide arrangement
Inventor: AVRAMIS EVANGELOS
IPC: H01P1/161
Filed: 1993-02-26
Abstract: In a waveguide arrangement for coupling energy fed into a waveguide inner space to two signal leads (3, 4), each of which is coupled to a probe (5, 6) projecting into the waveguide inner space, having a conductive resonant element (7) arranged centrally in the waveguide inner space with respect to its cross-section, which element is matched to the wavelength of the energy fed into the waveguide inner space in such a way that it can take up the energy as well as possible and that the energy taken up is coupled out on the probes (5, 6) which are arranged orthogonally to the longitudinal axis of the waveguide inner space and orthogonally to each other, to improve the cross- polarisation decoupling, provision is made of an electrically conductive separating element (8; 11) in the waveguide inner space, which element is arranged at an angle of approximately 45 DEG  in each case to both probes (5, 6), considered in the direction of the longitudinal axis of the waveguide inner space. <IMAGE>
Patent DE-4306847-A1 (DE)
Title: Electromagnetically operated valve
Inventor: ROMANENKO NIKOLAI
IPC: F16K31/06
Filed: 1993-03-01
Abstract: In known electromagnetically operated valves, the prescribed contact force of the closing element against its seat is produced by a load spring whose force effect on the closing element increases monotonously during its opening movement, which leads to a magnet system with a specific mass, size and degree of energy absorption. In the new valve, the intention is for a load device to safeguard the contact force but for its force effect on the closing element not to increase monotonously during its opening movement. The valve with electromagnet (8), load spring (5) and storage spring (12) contains a load device (13) which is attached between the housing (1) and closing element (6) or armature (10) and whose force effect on the closing element increases along the axis of the valve during 0...30% of the travel of the closing element or of the armature and subsequently decreases or is eliminated, and which can be realised in the form of     - a pressure spring mechanism,   - one or more rotary springs or bent spring plates,   - a cam mechanism,   - a magnet assembly.   The arrangement ensures in a versatile way a substantial reduction in the energy to be applied by the electromagnet and as a result permits a reduction in the mass, size and power absorption of shut-off valves for industry, mechanical engineering and transportation. <IMAGE>

Abstract: A substrate holder employed for MOCVD and supporting a wafer on which crystal growth proceeds includes a molybdenum holder body 1, a GaAs polycrystalline film 2 with a flat surface grown on a part of the surface of the molybdenum holder body where the wafer is absent, and an InP polycrystalline film 3 grown on the GaAs polycrystalline film. Each of the polycrystalline films is grown to a thickness of 0.3  mu m or more at a temperature higher than the epitaxial growth temperature of 575 DEG C. During the MOCVD process, the emissivity of the molybdenum substrate holder is settled at a value near the emissivity of the wafer on the substrate holder and, therefore, the decomposition ratio of the PH3 gas on the substrate holder is settled at a value near the decomposition ratio on the wafer, whereby the variation of the incorporation ratio of P atoms in the InGaAsP mixed crystal, i.e., the variation of the composition of the InGaAsP mixed crystal, is reduced and the run-to-run variation of the composition of the mixed crystal is reduced. In further embodiments an InGaAsP, at a temperature higher than 575 DEG C, and InP, at 400 - 550 DEG C, may be deposited on the molybdenum. The MOCVD apparatus includes a high-speed rotatable susceptor 200b; a substrate holder 300b disposed on the front surface of the susceptor; means for heating said susceptor; an inlet for supplying source gases; and a plurality of rotatable wafer trays 600a disposed on the front surface of the susceptor via the substrate holder, each wafer tray having a plurality of wings 600a1 to which a gas flow is applied. <IMAGE>

Patent DE-4431026-A1 (DE)
Title: Sensor for a motor vehicle
Inventor: SHINJO IZURU
IPC: F02P7/067
Filed: 1994-08-31
Abstract: A sensor for a motor vehicle is explained which is designed in such a way that a casing material for covering an area in the vicinity of the connection section between a sensor element and line wires is formed by injection moulding a thermoplastic elastomer. The casing material is used to obtain, at a low cost, a simple and reliable seal in the region in the vicinity of the connection section between the sensor element and the line wires. Since the elastomer has the elasticity of rubber, a concentration of voltage does not occur in the region of the line wires even if the sensor is subjected to vibrations. Disconnection of the line wire can no longer occur as easily.

Patent DE-4440048-A1 (DE)
Title: Fluorescent lamp control device e.g. for mixed light office work-place
Inventor: RUMP STEPHAN
IPC: H05B39/04
Filed: 1994-11-09
Abstract: A fluorescent light control device has a unit to adjust the supply voltage and a sensor to ascertain the illuminance generated from the lamp (e.g. fluorescent tube) and a further light source. The controller adjusts the voltage according to the sensor signal so that the total illuminance has a certain magnitude. The sensor is directly connected to the voltage controller and acts as a load impedance. Thus a deviation in the instantaneous received illuminance changes its impedance, causing the supply voltage to change accordingly and restore the overall illuminance to its previous value. The sensor is installed in the reflector system of the lamp.
